Key Features
Four heating elements are located on the chamber top, bottom and sides for enhanced temperature uniformity
Built-in vent port removes undesirable contaminants and moisture to extend the life of the element and unit
Rear of the chamber incorporates a 0.95cm (0.38in.) dia. port for monitoring chamber temperatures with independent measuring devices
Optional stainlesssteel shelf doubles load capacity (maximum temperature of 900°C)
Door safety switch stops power to heating elements when door opens
Thermocouple break protection cuts power to the heating elements, preventing a thermocouple failure runaway condition
Furnaces with B1, C1, and D1 control also use a mechanical overtemperature protection relay
